AutoCut® Line Head is rated 2.6 out of 5 by 75.

Rated 1 out of 5 by Miko from I believe in your product. Your chainsaws are awesome. So based on this I bought a fs38 trimmer from the get go the autofeed head was unreliable. It .The trimmer head is poorly designed. It will not advance line no matter how many times you bump it. I went back to my John deer/ stihl dealer and asked about a better head and was informed that this was the only head made for it. Unacceptable from a company of your stature. The trimmer itself is great.

Rated 1 out of 5 by KJM14 from Poor line feedingI have needed 3 different heads in my 1.5 years of ownership and I'm finally giving up on the autocut. A brand new spool works great until more line is needed. I am only rarely able to get the bump-and-feed to work and I spend more time respooling the line than trimming. Each of my 3 heads have had problems with feeding and fusing of the line. I thought it was me until I saw the other reviews on this product.Stihl, your customers are trying to tell you something.

Rated 1 out of 5 by Johnnykill63 from FragileI purcchased a new stihll brushcutter with one of these heads.Only use trimmer for roughly 2 hours a month but after 2 months I have noticed a lot of wear and tear on the head from using the tap and go feature.I reckon you would be lucky to get a full year out of a head based on this.

Rated 1 out of 5 by Kriam from This trimmer head does show any evidence of intelligent designThere has been nothing done to this design in 35 years other than to stack two spools on top of each other which just compounds the difficulty of rewinding, unwinding the line in a garage let alone in the field. The problem is the same as it has always been. There is no level wind mechanism to maintain the line in anything other than a rat's nest ( yet fishing reels manufacturers figured this problem our in the 1960's). Additionally, the beveled edges on the spool outlets consist of an material incompatible with plastic line causing pre-mature breakage at the point of projection, thus making it impossible for the bump and release spring mechanism to work even if the line is behaving on the spools ( the pinch points need to be inside the spool and of a softer material to allow for tensioning that occurs when heavier load is applied by thick or heavy grass or rocks etc. Whoever signed off on the design review and the QA of this product should be embarrassed. So now I have to go buy another line head adding to an already inflated cost. I am not convinced the supposed reliability is going to worth the pain and headache of the great Stihl.

Rated 1 out of 5 by davis2 from have to open the spool to get more line out, bump doesn't workTerrible product, the spool has to be opened everytime to let more line out. You can't wind line on top of each other and expect the line to come out.

Rated 3 out of 5 by peanut57 from Reliable but...I have to throw my hat in the ring with everyone else. I've purchased line trimmers before and I've not had the problems I've had with this particular line head. I absolutely hate trimming time because of it!

Rated 1 out of 5 by Stihlnotworking from What a painI've used this on my FS40. It worked decent for about 2 months, now it constantly has feed issues. I have to take it apart about every minute of use to manually feed the string through. The string constantly binds up as well.
